| 10 | NebulaGraph | TCP | 8888 | Backup and restore Agent service port. The Agent is a daemon running on each machine in the cluster, responsible for starting and stopping NebulaGraph services and uploading and downloading backup files. |
| 11 | NebulaGraph | TCP | 9789, 9788, 9790 | 9789 is the Raft Listener port for Full-text index, which reads data from Storage services and writes it to the Elasticsearch cluster.Also the port for Storage Listener in inter-cluster data synchronization, used for synchronizing Storage data from the primary cluster. The neighboring ports -1 (9788) and +1 (9790) are also used.9788: An internal port.9790: The port used for Raft communication. |
| 12 | NebulaGraph | TCP | 9200 | NebulaGraph uses this port for HTTP communication with Elasticsearch to perform full-text search queries and manage full-text indexes. |
